Dr. Cate's Takeaway

2/3 of career-ending injuries are a direct result of weak ligaments and tendons. Most athletes are leaving a gaping hole in their nutritional program that cannot be filled by whey or vegan protein powder — it can only be filled by homemade bone broth or collagen supplements.

Quick Summary

Athletes need strong joints, healthy tissues, and proper recovery — but not all supplements are equal. NSF Certified for Sport® ensures collagen is clean, accurately labeled, and free from banned substances. Most diets lack key collagen compounds, making third-party certified supplements essential. CB Supplements’ NSF Certified Multi Collagen delivers a full spectrum of collagen types to support performance and longevity.

Before competing in a championship, before receiving the title of champion, and even before simply showing up for competition, every athlete must have one thing.

Health.

Health: The One Thing Every Athlete Needs to Succeed

An injury or illness can have devastating effects on both immediate performance and long-term career prospects. Whether it’s the flu the night before a big game or a torn ligament that sidelines an athlete for months, staying healthy is paramount.

This is why athletes dedicate themselves to training, mobility work, diet optimization, mental resilience, and the right supplementation.

Without strong, supple joints, an athlete doesn’t stand a chance. Without joint-supporting nutrition, an athlete’s joints don’t stand a chance.

Collagen is for Athletes
Athletes, of all types, need HEALTH first and foremost

What is Collagen?

Collagen is a protein — the strongest, most durable protein in nature — found in all mammals, including humans. It is located in many parts of the body, including:

  • Hair, nails, and skin
  • Bones and muscles
  • Tendons and blood vessels
  • Vital organs such as the heart and lungs
  • The digestive system, most notably the small intestine

The Rejuvenating Magic (aka Science) of Collagen

The special amino acids in collagenhydroxyproline and hydroxylysine — are bioactive amino acids that stimulate the body’s natural repair process. These compounds have a synergistic effect that essentially reverses time in our joints, stimulating the cells in our tendons and ligaments to lay down more collagen, strengthening them from within.

The Big 3 Common Amino Acids in Collagen

Why Collagen for Athletes?

Muscle and connective tissue injuries (sprains, strains, and tears of ligaments and tendons) are the most common injuries for athletes. Our bodies manufacture collagen by combining amino acids from the foods we eat. However, there are two problems.

2 Problems Athletes face

  1. Most athletes don’t eat foods that contain the bioactive compounds that stimulate optimal collagen synthesis. See foods that contain collagen.
  2. The body’s collagen synthesis slows down after age 25.

Coincidentally, this is around the same age that many athletes peak in their careers. Ensuring proper collagen intake can help restore overall strength and flexibility in aging joints, preventing athletes from falling down the slippery slope of injury and poor health.

KEEP IN MIND
Collagen protein does not build muscle — that is NOT its superpower.

Why “Multi” Collagen?

Multi Collagen means collagen is sourced from multiple animal sources. Those sources are:

  • Beef
  • Fish
  • Chicken
  • Eggshell membrane

Most collagen supplements are only beef or chicken-based, meaning they miss out on providing all five key types of collagen (I, II, III, V, & X).

There is reason to believe a multi-collagen blend offers superior benefits over a single-source collagen because different sources provide unique amino acid combinations that support a variety of functions, from joint and tendon health to gut integrity and skin elasticity.

The Importance of Third-Party Certification

There’s no better way to ensure you’re taking the cleanest and safest collagen powder than to buy one with third-party certification. There is no gray area. Either a collagen supplement has undergone rigorous testing with an industry-leading third-party certification organization, or it has not.

Why is third-party certification important?

  • The government places responsibility on the manufacturer to ensure quality & accuracy — making GMPcompliance critical.
  • Some supplement companies use solvents, toxic ingredients, and banned substances, which may remain undetected without testing.
  • Without verification, supplement companies can use wildly inaccurate labels.

What does third-party certification guarantee?

  • The collagen powder is free of solvents, toxic ingredients, and banned substances
  • No unsafe levels of contaminants or heavy metals in the collagen
  • Label accuracy (7g of collagen = 7g of collagen!)
  • The product is manufactured in a GMP facility (more about what GMP certified means)
  • Annual or semi-annual quality audits of the GMP facility

Third-party Certification options for Collagen

An athlete should inspect a collagen supplement’s label and look for one of the following logos (below) to confirm third-party certification. Learn more about third party tested collagen where we explore these 4 most recognized certifications.

What is NSF?

Previously known as NSF International and founded as the National Sanitation Foundation, NSF (see website) protects and improves global human health. For 75 years, they’ve developed uniform, consensus-based national standards.

Understanding NSF Certified for Sport®

NSF’s global program helps athletes, dieticians, coaches, and consumers make safer decisions when choosing sports supplements.

NSF International is a globally recognized, independent, and accredited organization dedicated to protecting and improving human health. Their Certified for Sport® program is considered the “gold standard” in supplement safety and quality.

A product that is NSF Certified for Sport® must:

  • Be free from 270+ banned substances recognized by major athletic organizations
  • Match exactly what is printed on the label
  • Contain no unsafe levels of contaminants (such as heavy metals)
  • Be manufactured in a GMP-registered facility audited twice annually for quality and safety

Why NSF Certification Matters for Athletes

Athletes must be extra cautious when selecting supplements. Many products on the market contain hidden contaminants or unverified ingredient claims, which can lead to failed drug tests, unwanted side effects, or ineffective supplementation.

CB Supplements is the only NSF-certified product that gives athletes on a typical diet exactly what they’re missing: the full spectrum of nutrients necessary for proper growth and repair of all connective tissues.
